  • Copper Production: How Is Copper Made?

    Jan 14, 2019 · Solvent extraction involves stripping the copper from the pregnant liquor using an organic solvent, or extractant. During this reaction, copper ions are exchanged for hydrogen ions, allowing the acid solution to be recovered and re-used in the leaching process.

  • Separation of Copper and Nickel by Solvent Extraction ...

    Studies for stripping of copper from the organic phase using 180 g/l sulfuric acid showed that 98.5% copper can be recovered from solvent phase. This would permit the recycle of copper-stripped solvent for further use in extraction stage of the process.

  • Practical Aspects of Copper Solvent - ResearchGate

    2 RH (org) - is the stripped copper complex. Stripping of copper occurs when a strongly acidic solution (e.g., spent electrolyte at 180 gpl acid) is mixed with the loaded organic copper complex.

  • Control of an industrial copper solvent extraction process

    Fig. 1. Flow diagram of the copper solvent extraction process. In the extraction units, copper is extracted from the pregnant leach solution to the organic solution. In the stripping units, copper is stripped from the loaded organic solution to the electrolyte solution. The resulting rich electrolyte solution is led to the electrowinning process.

  • Solvent Extraction Stripping Methods

    To remain competitive, the domestic metals industry must not only make advances in mining methods, but also in ore processing. One processing advancement under investigation is the development of nonconventional solvent extraction (SX) stripping techniques such as hydrogen, hydrolytic, and precipitation stripping.

  • How to Strip Plated Silver Off Copper - Finishing

    How to Strip Plated Silver Off Copper. A discussion started in 2001 but continuing through 2017. 2001. Q. I am looking for a system that doesn't involve cyanide, nitric acid or machining to strip plated silver off of copper, so that the copper can be reused and replated as needed. Thank you, Peter. Peter Slade electrical controls mfgr ...

  • Copper & Nickel Solvent Extraction

    Residual ammonia was removed from the loaded solvent with a pH-controlled scrub. Nickel and copper loaded on the solvent were separated by selective stripping. Typical nickel strip circuit operation using electrolyte containing 90 grams per liter (g/l) Ni and 11.9 g/l yielded >99.9 pct Ni stripped from the solvent in five stages.

  • Identification and regeneration of degradation products ...

    The main degradation products of hydroxyoxime extractants from a long-term copper solvent extraction plant were examined and identified as 1-(2-hydroxy-5-nonylphenyl)propan-1-one and 5-nonyl salicylaldehyde. The degradation products could reduce the extraction isotherm, the stripping isotherm and the transfer of copper for the solvent extraction.

  • Solvent Extraction and Separation of Copper and Zinc from ...

    Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase ...
